Abstract

A system for testing an electronic device comprises a first output, a second output, and a third output connected to a positive input, an identification input, and a negative input of the electronic device, respectively. The system further comprises a switch comprising at least two dynamic contacts, each of which is connected to a resistor for the use of identification.

Claims

1. A system for testing an electronic device, the system comprising:

a first output, a second output, and a third output connected to a positive input, an identification input, and a negative input of the electronic device, respectively;

a first input and a second input connected to the first output and the third output, respectively;

a switch comprising at least two dynamic contacts and a static contact; and

at least two resistors, each of the at least two resistors having a first end connected to a first dynamic contact and a second dynamic contact of the switch, and a second end connected to the second output.

2. The system as claimed in claim 1, wherein the system further comprises an input interface connected to an external direct current power source.

3. The system as claimed in claim 1, further comprising:

a light emitting diode, a cathode of which is connected to the second input; and

a protective resistor connected between the first input and an anode of the light emitted diode.

4. The system as claimed in claim 1, wherein the second input of switch circuit is grounded.

5. The system as claimed in claim 1, further comprising an adjustable member to alter length of the system to correspond to length of the electronic device
